Why does my Audi A2's engine make a clicking noise when starting up?

I recently bought a used Audi A2 and noticed that the engine makes a clicking noise when starting up. Is this something I should be concerned about?

The clicking noise could be a sign of a weak battery or a faulty starter. It's important to have it checked by a mechanic to ensure that it doesn't lead to more serious issues.

It's normal for engines to make some noise when starting up, but if it's a loud and persistent clicking noise, it could indicate a problem with the engine's valves or timing belt.

Check the oil level and quality in your Audi A2. Low oil levels or dirty oil can cause the engine to make unusual noises. Get an oil change if necessary.
